I've had the opportunity to test out VisionTek's XG6 gaming mouse for a little while now, and while I'd never really thought I'd need anything other than my trusty Logitech MX 700 for all my mousing needs, I'm starting to think otherwise.
You notice two things when you first set your hand upon the XG6. The first is that there are a ton of buttons, the second that there is some sort of strange plastic piece sticking out behind the mouse that your wrist rests on. I'll admit that I tried to get used to that pad for some time, but I just couldn't. Thankfully, this is a removable piece, so I've stowed it away in case I ever change my mind.
